One of the reasons that LiIon tools are so much superior to previous tech
is that the batteries can supply very high currents.  NiCd tools with an
adapater can not take advantage of the higher output of the new battery,
and won't perform any better, except they will benefit for the longer run
time.  For some tools, that's fine, for others, it's a big limitation. You
will do well, if you go this route, to replace the tools you use most.  I
was not exaggerating when I said that 12V lithium outperforms 18V nicad.
It's lighter, more powerful, longer run times, and cheaper.
